The strongly correlated interactions found in twisted bilayer systems give rise to a range of exotic phenomena but due to range of factors it is challenging to develop theoretical models that can faithfully describe the underlying physics. Here, the authors provide an analysis of the chiral limits of perturbed Dirac field theories that are relevant to C3-symmetric twisted bilayer graphene and transition metal dichalcogenides homobilayers. They identify two possible scenarios and show that flat bands are a more likely phenomenon in the latter system

Understanding the hybridization due to orbital overlap in solids allows justification for adjusting electron correlation and hopping integral under the Hubbard model. This work links spatial-overlap-driven to energetic-overlap-driven hybridization from perovskite oxides by resonant inelastic X-ray scattering at La N_4,5 edges.

Condensates with a shell can be formed by liquid-liquid phase separation and can burst like viscous bubbles by nucleation and growth of a hole in the shell surrounded by a rim. The authors develop a model to extract a broad range of rheological properties for spherical shells to understand the conditions for bursting.

When a pulsed laser interacts with tissue, the molecules in the sample get excited to a higher energy state and relax either nonradiatively, leading to thermal damage, or via de-excitation processes, frequently associated with photodamage. Here, the authors explore how different photodamage mechanisms unfold across a spectrum of intense near-infrared femtosecond pulses.

Modulating the height distribution of nanostructures imparts multiple functions to the surface, but the recent methods are too complex for rapid mass production. This paper introduces a framework combining human and artificial intelligence to design multi-functional surfaces with tailored properties like color, friction, and bactericidal effects using capillary force lithography.

Despite the importance of shear-thinning rheology which many glassy materials universally experience under shear flow, significant discrepancies between theoretical explanations and experimental observations have remained unaddressed for over two decades. Here the authors renovate the theory to address these discrepancies and establish a universal mechanism of shear thinning.

Synchronization between self-sustained oscillators is ubiquitous in nature and engineering, and it is generally accepted to occur due to weak interactions between the oscillating objects. The authors challenge this paradigm by presenting a theoretical higher-order phase model for non-weak coupling validated through experiments.

Similar to optical spin-orbit interactions (SOIs), acoustic SOIs are anticipated to offer fresh perspectives and capabilities for acoustic manipulation beyond conventional scalar degrees of freedom. Here, the acoustic extrinsic SOI is observed in a double spiral acoustic beam (DSAB), as evidenced by the rotation of the spatial intensity pattern along the propagation axis.

Recent experiments on the Kagome superconductor (SC) CsV3Sb5 indicated 6e-charge flux quantization, which may impact our understanding of the electron pairing in SCs. The authors propose a multicomponent Landau-Ginzburg theory to explain the observed phenomenon, concluding that it is likely related to an exotic Higgs-Leggett collective mode involving three Cooper pairs in an intermediate phase.

The topology of braids and knots plays a central role in the understanding of many physical systems. In this paper, the authors demonstrate that unsupervised learning can be used to fully classify the braid group and knot topology associated with the bands of non-Hermitian systems, without requiring any prior information such as mathematical knowledge of topological invariants

When implemented on quantum computers, lattice gauge theory should be able to address significant new scientific questions about quarks and gluons. The authors of this paper replace the traditional Cartesian lattice by one that has unique symmetry properties, and they use this new lattice to perform an error-mitigated quantum computer calculation.

By using the sweeping cluster quantum Monte Carlo algorithm, the authors reveal the complete ground-state phase diagram of the triangular-lattice fully packed quantum loop model. They discover a hidden vison plaquette phase between the known lattice nematic solid and the even \({{\mathbb{Z}}}_{2}\) quantum spin liquid (QSL) phase, which had been previously misinterpreted as the QSL, and explain how to detect it experimentally.

Large structure in the Universe, such as galaxies, are believed to form by a process called violent relaxation, which occurs over millions of years. The authors present a nonlinear optics experiment which shows direct observation of violent relaxation, whose evolution can be related to the equations governing galaxy formation.
